Case Discussion
Hydropneumothorax describes air and fluid within the pleural space. It has a typical straight appearance at the air-fluid interface, as opposed to the meniscus of a purley fluid filled pleural collection.
Two of the most common reasons are in trauma and in the early stages following pneumonectomy, as the thorax cavity fills with fluid following surgery.
